Description
Recently, the viewer's handling of downloaded and queued outfits was updated with the addition of setForceRefresh() to ensure the outfit list remains consistently up to date. While this improves accuracy, it introduces performance issues for users with very large outfit collections, when they open outfits list. Users approaching 800-1000 outfits may experience significant slowdowns, as constant refreshes can cause FPS to drop to single digits or even freeze the viewer for several minutes.
In testing with an alternate account containing approximately 2,400 outfits, FPS dropped from around 200 to 5 for 2–3 minutes. This issue affects both the current Second Life Viewer (7.2.1.17108480561) and Firestorm Beta 7.2.2 (79314).
